The New York Times reports that while St. Hubert hasn't confessed to any of the crimes, he has made "references to Satan," despite his speech largely consisting of incoherent ramblings. Furthermore, the New York Post reports that St. Hubert allegedly told a homeless shelter worker that he had done "bad things" the night that he killed Prince Joshua Avitto and wounded Mikayla Capers.

He added a chilling revelation: "The devil made do it." The Post adds that just before he was arrested near his mother's Jamaica, Queens home, police had just watched him engrave "$ KILLZZ I WILL BK" on a stop sign.

According to the Daily Intelligencer, St. Hubert is a paranoid schizophrenic who spent five years in prison for trying to strangle his mother with an electrical cord, as well for attacking a female corrections officer.

St. Hubert's sister, Judith Perry, told the New York Daily News that she "begged" officials to get her brother help for his mental illness before and after his May 23 release from prison. "I spoke to the social worker in regards to his mental capacity and when will he be able to see a doctor," she told the Daily News. "They told me it doesn’t happen right away."

In addition to the attack on Avitto and Capers, police suspect St. Hubert killed 18-year-old Tanaya Grant-Copeland in East New York on May 30, and stabbed a man at a Chelsea subway station on the morning of the day he was arrested. The Daily Intelligencer notes that his MetroCard places him at the scene of the latter crime.

At the moment, St. Hubert has only been charged for second-degree murder and second-degree attempted murder for Sunday's incident.
